Arguments on the internet are held public most of the time + it's all public record. Personal insults are generally not acceptable. But when is it personal and who decides what's personal and what not? Where is the point when insults are the least important part of the issue? Should the insulted person always take insults personal regardless what issue at hand?
I understand that sometimes an argument about an issue in reality is a battle of egos. But, seriously, Intel trying to wiggle themselves out of the noose with it's not a bug it's a feature PR stunts, I think insults are as appropriate as "thank you" and "have a nice day". So, if anyone says or does something stupid for no apparent reason, questioning the sanity of their decision making by calling them a moron is the way to go, imo.
Most people are going to take it personally, especially when it’s public in front of their peers, and since it’s so lazy and unhelpful there’s no benefit from doing that rather than, well, anything constructive
